6.33.3 Limiter Soft Ramp Disable
Configures an override of the digital soft ramp setting.
6.34 Status (Address 29h) (Read Only)
For bits [6:0] in this register, a “1” means the associated error condition has occurred at least once since the
register was last read. A”0” means the associated error condition has NOT occurred since the last reading
of the register. Reading the register resets these bits to 0.
6.34.1 HPDETECT Pin Status (Read Only)
Indicates the status of the HPDETECT pin.
6.34.2 Serial Port Clock Error (Read Only)
Indicates the status of the MCLK to LRCK ratio.
Note: On initial power up and application of clocks, this bit will report ‘1’b as the serial port re-synchro-
nizes.
6.34.3 DSP Engine Overflow (Read Only)
Indicates the over-range status in the DSP data path.
6.34.4 MIXx Overflow (Read Only)
Indicates the over-range status in the PCM mix data path.
LIMSRDIS Limiter Soft Ramp Disable
0 OFF; Limiter Attack Rate is dictated by the DIGSFT ( “Digital Soft Ramp” on page 46 ) setting
1 ON; Limiter volume changes take effect in one step, regardless of the DIGSFT setting.
